The drawings show one form of device emlike parts throughbodying the invention. In this Construction there is a paper roll supporting device consistigof a movable or rotatable member carrying, aplurality of rolls of paper andarrange'd s o that a new roll may be brought into operative position when the preceding roll is about exhausted. For purposes of illustration, there is shown a device of this kind consisting of a. rotatable shaft 1 which is provided with a plurality of arms 2 arranged in pairs spaced apart along the shaft, the rolls of mounted 'ctween these arms'.--

s One or more roll engagng devices arev 'the' device which uses it. 3

:I have shown the roll engaging device in the drawings as consisting of a belt which is, held in position by suitable engaging devices.

i In the construction shown, thereis an engaging device 7 at the bottom and an engaging device 8 at the top and the intermediate engaging devices 9 and 10 The roll engaging device in the particular Construction illustrated, is shown as a belt' and it may be a. running belt or a stationary device. If it is a running device, the engagng devices 7 and 8, 9 and '10 are suitable direction changing devices, preferably pulleys or rollers. The device may be driven from any suitable source of power, such as the machine to which the 'paper is delivered or to some separate source. Asimple manner of drivng the device is to drive the shaft 11 which carries the pulley 8. This shaft is shown as being provided with a beveled gear 12 which engages a beveled gear 13 on a shaft 14: driven by a belt 15 connected with a suitable source ef ower. v V

weight 16 is connected with' a' direction changing device 17 which enga 'es the paper' engaging device 6. Some suitsible means is provided for rotating the roll supporting dei mechanisn used in delivering the paper to provided which engage the web of the paper aper 3, 4, and 5 being rotatably;

preferably arranged so as to give a large contact area between the roll and the roll engaging device 6 and the weight 16 keeps the roll engaging device taut so as to secure the proper frictonal contact.

In the Construction illustrated, the new roll of paper is brought up to speed by engagement with the web 18 of the roll from which paper is being delivered to the device which uses it and the apparatus is so arranged that this new roll may be brought up to the desired speed while the apparatus is running at high speed and the web of the new roll connected with the web of the expiring roll at this high speed. The means for securing this in the particular Construction illustrated is as follows: s

The arms with which the rolls of paper are connected are provided with spindles 19 which engage such rolls by engaging the hollow core 30 thereof (see Fig.. 4). These spindles are rotatably mounted -npon the arms 2 as shown in Fi 4. Some means is provided for holding the new roll so that it will not start rotating until it has been moved into sucient contact with the web of the expiring roll to cause the roll engaging device 6 to exert a suilicient pressure to bring the new roll up to the proper high speed in a single revolution. This is accomplished in the Construction shown by connecting to one or both of the s indles 19 of each roll, a suitable holding an releasng device which i holds the roll againstrotation until theforce acting on it through the agency of the web of the expiring roll and the 'pressure of the roll engaging* device is sufiicient to give' it the rate of acceleration necessary for the proper functionng of the device.

This holding and releasing device consists of a member 20 attached to the spindle 19 in any desired manner so as to rotate therewith. It may be integral with the' spindle or' may be -sutably connected therewith. drawings, it is shown as separate from the spindle and connected therewith by fastening devices 21. The member 20 is provided with one or more notches 22. A holding and releasing member 23 hasa part which projects into one of these notches when the roll is being held. The member 23 is shown as rocking about a pivot 24. The member is pret erably provided with rollers 25 and 26 at the opposite ends thereof. The pivot 24: is held in position by the supporting piece 27 attached to the plate 28 by the fastening pieces 29 and 30. lVhen the member 25 is in engagement with the member 20, the roller 26 is in engagement with the stop 31, (see Fig. 5). This stop is connected with a sliding member 32 mounted in guides 33, 34.

To release the holding and releasing member 23, the stop 31 must be moved toward the guide 34:. This movement of the stop is resisted by some suitable resisting device such In the as the spring 35. The sliding member 32 is preferably provided with hand pieces 36 and 37 by which it may be easily moved. The member 23 is provided with a spring 38 which is connected at one end to a fixed part such as the support 29 and at the other end to the member 23 and is arranged to move the mem ber 23, when released, back into its looking position that is with its end in the slot 22. The stop 31 is preferably provided with a beveled face` 39.' lVhen the roll from which paper is being supplied is about exhausted, the roll support consisting of the shaft 1 and the arms 2, is moved in the direction of the arrow shown in Fig. 2 so as to move the new roll 4 into contact with the web 18 of the expiring roll 3 and as this movement is continued, the web 18 and the roll engaging device 6 exerts an increasing pressure on the new roll but thenew roll is held against rotation by the engagingand releasing member 23 in the notch 22.

'When the new roll 4 which has an adhesive 40 attached to the end of the web thercof (see Fig, 2) has been moved a sufficient amount so that a suflicient pressure is applied to it to give itthe proper speed in one rotation, the holding and releasing device 23 is released and the roll is then set in motion responsive to the engagement therewith with the web 18. The adhesive 40 is preferablyplaced so that the roll may be given .substantially a complete rotation before the adhesive comes in contact with the web 18. If the release of the roll 4 has been delayed until suiicient pressure has been applied to it, the speed of the web of this roll 4:, when the adhesive reaches the web 18 of the expiring roll, will be substantially the' same as the web 18 and the web of the roll 4 will thenbe automati-` callv attached to the web 18. u

The web 18 of the roll 3 is then broken and the delivery of the paper will then proceed from the new roll`4. It will` be seen'that by means of this Construction the webof the two rolls may be connected' together while the printing press or other machine is being run at a high speed, that is; this Construction wil p make a high speed flying paster.

' The releasing of the holding and releasing device 23 is regulated by the spring 35 which has an adjusting device 41 consisting of a nut threaded on the sliding member 32 so thatthe pressure exerted by it may be regulated.

lVhen the member 23 has one end in the not-Ch 22 and the other end against the stop 31 it can only be released by moving the member 32 and the stop 31 in the direction of the guide 34 and the amount of pressure on the roll required to do this is regulated by the spring 35.

-When a sufcient pressure" is being exerted on the roll 4 by this contact with the web 18 and the pressure of the roll engagng device 6, the roller 26 will exert a sufiicient pressure on the stop 31 to move it. The member 20 will then exert a pressu re on the roll 25 and the holding and releasing member 23 will be moved out of the notch 22. The roll 26 ?will ber 20.

When it is desired to move the member 23 to its looking position, the sliding member 32 is moved so as to pcrmit the roller 23 tovmove back of the stop 31 to the position shown in dotted lines in Fig. 5. The retracting spring 38 will cause this movement when the stop is moved to the proper position. The device is then ready for operation, as hereinbefore described.

Any suitable means may be used for moving the roll .supporting device. As herein shown, this is accomplished by neans of a motor which is connected to the shaft 1 in any suitable manner. As hcrein shown, the motor is provided with the pinion 1 1 which engages a gear 45 on the shaft 46 carrying: the worm 47 which engages a worm gear 48 on the shaft 1 v lt will be seen 'that when the motor is.

operated, the shaft 1 will be rotated so as to move the rolls of paper successively into operative position as' desired. The adhesive material on the new roll instead of being' placed at the end of the web thereof, is preferably placed at a suiicient distance 'from the end .so that if there should be any slidinr between the adhesive material and the web of the exhausted roll, the adhesive material will simply move along; this end' section of the new roll and none of it will be exposed on the web of the exhausted roll.

T have described a particular Construction embodying the invention with a view of mal(- in: its application clear but it is. of course. evident that the parts may be varied in many particulars without departinz froni the spirit of the invention as embodied in the claims hereto appended. I therefore. do not limit mvselt to the particular construction shown.

T he use and operation of my invention are as follows: v

`When the rolls of paper are placed in position and the device started up, the narts in the position shown in Fig. 1. When the roll 3 is about exhausted. the motor 43 s onerated so as to move the roll 5 toward the web 18 ot the roll 3. The roll 4: is so positioned that the adhesive material 40 is at a point where the roll may be moved substantiallv a complete revolution before such adhesive strikes the web 18. As the roll 4 is moved into contact with the web 18, which is being pulled into the machine with wh ch it is being; used, pressure is anplied to the roll and a force is also applied to said roll tending to rotate it. The holding and releasing member 23 being now in the notch 22 holds the roll against rotation. As the roll is moved farther along, pressure is being applied to its face by the roll engaging mem- The parts are arranged so that When the pressure is sufficient to brought up to the proper speed by approximately onerevolution, the holding and re-' leasing member 23 is forced out of the notch 22 into the position shown in full lines in Fig. 5, and the force tending to rotate the roll 4 is then free to do so and this roll is rotated and brought up to speed in one revolution and the adhesive material 40 engaging the web 18 causes the web of the new roll 4 to become attached to the web of the ex- 'hausted roll 3, the delvery of the paper being then transferred to the roll 4. The paper from the roll 3 is severed at a point between the roll 4 and the roll 3 in any convenient manner as by means of the hand of the operator or the like.

Fig. 3 shows the new roll after it has been 16 pressing the web 18 against the new F cause the roll &to be set in motion andjust before the adhesive thereon engages the web 18 of the exhausted roll. The roll engaging member 6 may be run as a belt or may be stationary, its function being to press the web 18 of the exhausted roll with suflicientforce against the new roll. A sufiicient pressure may be applied to the roll 4: by the web alone where the web of paper is of sufiicient .strength, and in that case the roll engaging member 6 may be omitted. The rotation of the expiring roll may then be stopped inof the exhausted roll any suitable manner as by any ordinary brake applied to it.
